IM PROVEM ENT. IN WHEEL-PLOW-S.

Specification forming part of Letters Patent No. 211,958., datedFebruary 4, 1879; application filed June 20, 1878. i

To all whom it may concern:

Be it known that I, ALBERT D. BLANCHARD, of Hutchinson, in the county ofReno and State of Kansas, have invented a new and useful Improvement inWheel-Flows; and I do hereby declare that the following is a full,

clear, and exact description of the same.

The invention is an improvement in the class of wheel-plows which may beraised and lowered by means of a lever or levers, and is moreparticularly an improvement upon the plow forming the subject of LettersPatent granted G. W. Hunt, July 21, 1874.

The invention consists, broadly stated, in adjusting the rear end of along slotted lever, to which the plow-beam is pivoted, by means of aneccentric-lever which is pivoted to the elongated verticalplow-standard, and thereby raising or lowering the plow itself, so as tomake it run at any required depth, or to take it out of the groundaltogether, as required when moving it from one place or field toanother. An adjustable ratchet-plate is attached to the eccentric-lever,which engages a pawl on the aforesaid slotted lever, and thereby formsthe device which holds the parts locked and the plow fixed in anyadjustment.

In the accompanyingdrawings, forming part of this specification, Figure1 is aside view of my plow. Fig. 2 is a detail crosssection on line as00, Fig. 1. Fig. 3 is a side view of the adjusting mechanism detachedfrom the machine and enlarged. Fig. at is a cross-section of theadjusting or eccentric lever on line 3 y, Fig. 3.

a, is the long curved slotted lever to which the plow-beam is pivoted,and which is connected with a truck or wheeled axle by a detachablepivot-bolt. The standard 1) passes through a slot in said lever, and toit is pivoted the eccentric d, by means of which the lever a is raisedor lowered. 6 represents the lever by which the eccentric d is worked. 0

represents the ratchet attached at the upper end to the eccentric at andstandard I) by a bolt passing through the ratchet c, the eccentric d,and the standard b, which bolt is repre sented by p. n represents thecatch on which ratchet works, attached to lever a, by a bolt. frepresents the lever connected with the ratchet and controlling it. m isthe connect; ing-rod between lever f and ratchet 0. g is thelspringbetween the two levers to throw out lever f, and thus throw the ratchetupward, so as to connect with the catch n.

The ratchet c and eccentric d are connected in the front by a boltpassing through the eccentric cl, and working in a slot, 8, in ratchetc.

What I claim is 1. The combination of the eccentric d, lever e, andratchet c with the slotted lever to, catch a, standard I), plow-beam h,and frame, sub stantially as shown and described.

2. The eccentric 6?, made rigid upon the lower end of the lever e, andprovided with the ratchet-plate 0, having a slot, 8, and being actuatedby the spring-catch f, substantially as shown and described.
